Forget and ignore any "investigations". Gravity is the boss: what goes up must come down. No matter how well the airplane is designed; no matter how it can potentially perform in "dog-fights"; no matter how well the pilot is trained if things go amiss it comes down and causes and, not always, creates great destruction. People have posted that these planes are designed to perform like this, and the pilots are trained to fly under these conditions; however, guess what? Sometimes, maybe not often, things go terribly wrong. Investigations will most assuredly declare that "Lessons will be learned". Ban these performances or not? Probably not: after a few weeks this incident will be forgotten by most of us.
